Symphonies in Steel:
Bay Bridge and the Golden Gate

By John Bernard McGloin, S.J.
Professor of History
University of San Francisco

San Francisco can rightly claim to be one of the skyline cities of the nation. Situated at the tip of a peninsula and built in considerable part upon hills, the city is surrounded on three sides by the waters of the Golden Gate, the bay, and the Pacific Ocean. From the air, one notices a thread leading eastward across the Bay, and another leading northward across the Golden Gate. These two threads are, of course, two of the truly great bridges of the world: the San Francisco-Oakland Bay Bridge, opened in late 1936, and the Golden Gate Bridge, opened the following summer.

A plaque is located at the southeastern corner of Montgomery and Jackson streets in San Francisco; the text of the inscription reads as follows:

On this site the first San Francisco Bridge was constructed in 1844 by order of William Sturgis Hinkley, Alcalde of Yerba Buena. It crossed a creek which connected Laguna Salada with the Bay and was regarded as a remarkable structure and great public improvement as it shortened the distance to the town’s Embarcadero at Clarke’s Point.

San Francisco and adjacent areas have come a long way in the matter of bridges since the Hinkley span. Within the 450 square miles of landlocked harbor, San Francisco Bay has eight major highway bridges, including four of the world’s greatest steel bridges, as well as two railroad bridges. Four of these bridges, San Francisco-Oakland, Golden Gate, Richmond-San Rafael, and Carquinez Straits, are rated among the ten most notable structures of their kind in the world. Other bridges include the San Mateo-Hayward, Dumbarton, Southern Pacific’s Suisun Bay and Redwood City-Newark railroad crossings, as well as the Antioch , Bridge. Easily the most important of all these are the two bridges that were completed in 1936 and 1937.

Mention was previously made of Emperor Norton; during his quixotic reign as “Norton I, Emperor of North America and Protector of Mexico,” he issued a “decree” that San Francisco Bay be bridged immediately. This was to remain unfinished business until long after the emperor, as well as his two dogs, Bummer and Lazarus, had retired from the civic scene. However, when at length the emperor’s mandate was fulfilled, presumably even his imperious self would have been satisfied.

Modern photograph of the San Francisco-Oakland Bay Bridge The Bay Bridge is the longest steel high-level bridge in the world. As mentioned earlier, the Yerba Buena Tunnel with its diameter of 58 feet, which forms part of the highway between San Francisco and Oakland, is the tallest bore in the world. Additionally, the Bay Bridge can boast of the fact that its construction required the greatest expenditure of funds ever used for a single structure in the history of man. Its foundations extend to the greatest depth below water of any bridge built by man; one pier was sunk at 242 feet below water, and another at 200 feet. The deeper pier is bigger than the largest of the Pyramids and required more concrete than the Empire State Building in New York.

On Thursday, November 12, 1936, at 12:30 p.m. the Bay Bridge was opened to vehicular traffic; its construction had continued for exactly three years, four months, and three days. It was the result of years of discussion and planning on the part of those concerned with providing means of transportation other than by ferry between San Francisco and the East Bay. The Hoover-Young Bay photo of California Governor Clement Calhoun YoungBridge Commission (named after President Hoover and California’s Governor C.C. Young) began sessions in Sacramento in October 1929. With the cooperation of various state agencies, an engineering and traffic study was made. Finally, the present route was agreed upon and the considerable financing of the project was explored. As finally constructed, the Bay Bridge is 43,500 feet or 8 1/4 miles long, from end to end of the approaches. The bridge proper, including the Yerba Buena crossing, is 23,000 feet or 4 1/2 miles long. On the San Francisco side of Yerba Buena Island, the structure consists of two complete suspension bridges with a central anchorage in the middle. The towers of the suspension rise 474 and 519 feet above water. Over the east channel, the span continues with one main cantilever span of 1,400 feet and, east of this, five truss spans each measuring 509 feet. The two cables supporting the suspensions are each 28 3/4 inches in diameter, and each contains 17,664 wires; the total length of these wires is 70,815 miles, which is enough to encircle the earth three times. The concrete and steel used in building the Bay Bridge would build thirty-five San Francisco Russ Buildings plus another thirty-five Los Angeles City Halls or L.C. Smith buildings in Seattle. Each of the two principal towers represents a construction job equivalent to building a sixty-story skyscraper.

The chief engineer for the entire project was Charles H. Purcell (1885-1951) whose competency was matched only by his modesty. Assisting him was Charles E. Andrew as bridge project engineer and Glen Woodruff as designer. Total cost of the bridge, including interurban electric rail facilities (since unfortunately abandoned), amounted to $79.5 million. This was financed by sale of 4 and 3 percent revenue bonds, which were purchased by the Federal Reconstruction Finance Corporation. In addition to these bonds, the California State Gas Tax Fund loaned $6 million for the building of the approaches; both sums were eventually repaid from toll revenues. (In 1958, a four-year reconstruction program was undertaken at a cost of $35 million.) Decreasing patronage of the interurban trains had caused the Key System Lines to abandon this service, leaving buses to handle the load exclusively. This reconstruction involved track removals, conversion of each deck (lower and upper) to one-way motor vehicle traffic, and the lowering of the lower deck of the bridge by 16 inches through the Yerba Buena Tunnel. The maintenance of such a colossal structure keeps a legion of persons constantly at work. No matter from what angle the San Francisco-Oakland Bay Bridge is viewed, it will always remain a symphony in steel.

For years, the Golden Gate Bridge held the title of longest suspension bridge in the world. Despite the claims that the Mackinac span, which connects the greater part of Michigan with its upper peninsula across the Straits of Mackinac is longer, the question is best resolved by settling what is meant, indeed, by “longer”: actually, the Mackinac suspension is supported by a single span of cables 8,344 feet in length as compared with 4,200 for the Golden Gate Bridge. However, the center span of the Mackinac Bridge is exceeded in length by both the Verrazano Narrows Bridge in New York City and the Golden Gate Bridge. The claim of “longest” for the Mackinac is based upon the distance between cable anchorages, while the Golden Gate figure is based upon the actual distance between its towers. Rival claims, though, do not seem to be of great importance, since all will admit that, just as is true of its sister span across San Francisco Bay, the Golden Gate is “quite a bridge,” the fulfillment of a dream and a vision had by one man: it is the “bridge that couldn’t be built.”

This “preview” was followed the next day by dedicatory ceremonies which culminated in the cutting of a ceremonial barrier, after which an official cavalcade of automobiles traversed the span; the rest of that day was devoted, again, to pedestrian traffic, and the regular flow of vehicular traffic started the next day. It has been written that

Residents of the San Francisco Bay area feel this bridge as an entity and have a section for it. They admire its living grace, and its magnificent setting. They respond to its many moods—its warm and vibrant glow in the early sun, its seeming play with, or disdain of, incoming fog, its retiring shadowy form before the sunset, its lovely appearance in its lights at night. To its familiars it appears as the “Keeper of the Golden Gate.”[l]

The Golden Gate Bridge is the result of the long-term determination of the people of six California counties who, eventually, formed themselves into a Golden Gate Bridge District comprising the city and county of San Francisco, Marin, Sonoma, and Del Norte counties, as well as a portion of Napa and Mendocino counties. Since it had long been apparent that the bridging of the Golden Gate, despite the many problems its construction would entail, would mean an effective opening up of the counties north of San Francisco, much planning went into the implementation of the visions and dreams of the members of the Bridge District. In 1928, earlier efforts culminated in the incorporation of the Golden Gate Bridge and Highway District; in November 1930, the voters of the concerned counties passed a $35 million bond issue to finance the building of the bridge, while pledging the property of these counties as security for the payment of the bonds. For many years, Joseph Baerman Strauss (1870-1938), a distinguished engineer with many bridges to his credit, had dreamed of raising a span across the Golden Gate. One who contemplates his many activities realizes that Strauss was much more than merely a competent structural engineer, although he certainly was that: he was also a poet, a seer, and a man of vision and it seems that all these qualities sustained him in the fulfillment of his dream; it is equally certain that he had to live with the skepticism of his peers who kept repeating that “Strauss will never build his bridge, no one can bridge the Golden Gate because of insurmountable difficulties which are apparent to all who give thought to the idea.” But Strauss held fast to his vision, and, even though he survived only a year after the opening of his bridge, he did live to bring it to completion.[2]

Photograph of Joseph Strauss. Photo by Peter StackpoleConstruction of the bridge took four and one-half years and the work began on January 5, 1933. The resulting span has been much admired for its magnitude and its graceful beauty. At mid-span the bridge is 220 feet above the waters of the Golden Gate; it is about a mile across and there is only one pier in the water which, incidentally, was built under most discouraging circumstances, as Engineer Strauss could testify. This pier is only 1,125 feet from shore; the distance between the two towers that support the cables which, in turn, support the floor of the bridge, is 4,200 feet. These two cables are 361/2 inches in diameter, the largest bridge cables ever made. Each cable is 7,659 feet long and contains 27,572 parallel wires, enough to encircle the world more than three times at the equator. Fortunately, solid rock was found at each end of the Gate and huge pockets were excavated in this rock to form a setting for the concrete anchorage blocks, each of which contains 30,000 cubic yards of concrete. Among the engineering problems that had to be faced in the building of the bridge were those that arose from the exposed nature of any such structure, for it has to withstand winds and gales coming from the often far from peaceful Pacific Ocean. It was so designed that, in the most unlikely event of a broadside wind coming at it with a speed of one hundred miles an hour, the bridge floor at mid span might swing as much as 27 feet.[3]

Practically all of the Golden Gate Bridge is located within the city and county of San Francisco (as is the Golden Gate itself). The two towers rise an impressive 746 feet which means that they are 191 feet taller than the Washington Monument. In 1884, a poet thus saluted the Golden Gate:

Wide Thy Golden Gate stands open to all
Nations of the world,
Free beneath its stately portals
All flags are in peace unfurled.
Beauteous Gate, when loitering Sunset
Covers Thee with burnished gold.
Mighty Gate, when surging ocean Thy
Strong cliffs alone withhold.

Treacherous Gate, deceiving many with a
Name most fair-Blessed Gate, where millions
Find the golden boon of liberty. [4]

At the completion of his mighty bridge, Joseph Strauss penned an impressive ode which he entitled “The Mighty Task Is Done”; it epitomizes his personal travail in building the bridge and makes of the structure almost a living thing. From his poem, these lines give evidence of the dedication of the man who brought the bridge from his brain and heart as well as from his drawing board:

At last the might task is done;
Resplendent in the western sun;
The Bridge looms mountain high

On its broad decks in rightful pride,
The world in swift parade shall ride
Throughout all time to be.

Launched midst a thousand hopes and fears,
Damned by a thousand hostile sneers.
Yet ne’er its course was stayed.
But ask of those who met the foe,
Who stood alone when faith was low,
Ask them the price they paid.
High overhead its lights shall gleam,
Far, far below life’s restless stream,
Unceasingly shall flow....

With the completion of the two giant bridges, it was but natural that a proud San Francisco would again wish to call the people of the world to itself; so it was that another world fair, this one called the Golden Gate International Exposition, was planned and brought into being. Several years previously, a movement to develop an airport site by constructing a fill over the shoal area adjacent to Goat Island (Yerba Buena) was started. Although the airport was finally placed elsewhere, the planning resulted in a man made island (called “Treasure Island”) on which was staged the exposition.

When the voters of San Francisco decided to have such an exposition, the question of financing the necessary engineering work was happily resolved. In late 1935, the city of San Francisco succeeded in having the project approved as a Works Progress Administration (WPA) project. This authorization, including 20 percent to be furnished by San Francisco, amounted to $3,803,900. After further study, the WPA concluded that the nature of the work required was such that it could not handle the project. The Secretary of War approved the request that its execution be undertaken by the Army Corps of Engineers. While a group of such specialists applied their talents to the reclamation of the “Yerba Buena Shoals,” the day-by-day details were efficiently cared for by Colonel Fred Butler, U.S.A., who had years of army engineering experience behind him at this time. The fill to form Treasure Island was obtained by dredging operations; the island covered an area of 400 acres, 5,520 feet long by 3,410 feet wide.

Meanwhile, the San Francisco Bay Exposition Company was formed with Leland W. Cutler as president. He was greatly aided from the beginning by George Creel, who was appointed United States Commissioner of the Exposition. By 1938, 1,200 men were employed in horticultural work on the newly born Treasure Island; they planted 400,000 bulbs, 800,000 seeds, and 4,000 trees. It then remained for the architects and artisans to accomplish their respective tasks. The international dimension came only gradually as Leland Cutler persuaded those concerned that an invitation should be extended to other countries to join in the celebrations. A subtitle, “A Pageant of the Pacific,” was added to the title of the exposition, and gradually its international status was assured.

Gov. Culbert L. Olson - Life Magazine cover, 1938 On Monday, February 18, 1939, the “Magic Isle” as many called it, was opened to an expectant public; special ceremonies were presided over by Governor Culbert C. Olson who appeared before a decorative Golden Gate Bridge portal to the exposition armed with a large key. With the opening of this portal, the exposition commenced. Although not all the exhibition halls had yet been completed, there were enough attractions, plus the novelty of the site itself, to satisfy those who thronged the island on opening day. Notable were the Tower of the Sun with its Elephant Towers, while many came to regard the Federal Building as the most striking of all the buildings. The landscaping and horticultural results attracted much favorable comment. The extensive art work also merited approval; among the best murals were those of Millard Sheets depicting California history. These were supplemented by some borrowed European masterpieces. When one added to the above features the scientific exhibits and recreational areas, it was apparent that there was “something for everyone” in the Golden Gate International Exposition. During its run, the exposition attracted 17 million visitors. However, it was not a financial success; in October 1939, the Pageant of the Pacific closed its gates, six weeks early and $4,166,000 in debt. It was decided to reopen the exposition in 1940 in the hope of recouping these financial losses. This was done in the spring of 1940 when Europe was in the convulsions of war. However, the Fair went on as planned; when it finally closed its doors in September 1940, an admirer wrote:

Before we expected it, the day came to close the gates. It was a sad occasioned especially for the rest of us who had found refreshment on Treasure Island. When the final bills had been paid, it would be recorded that the Golden Gate International Exposition, like so many others before and since, had lost money. The staff compiled a final report, cleaned out the files and drifted away. [5]

Today Treasure Island is owned by the Navy. After Pearl Harbor, the site was turned over to the federal government by San Francisco and it is now one of the West Coast’s main naval installations. Three of the expositions’ permanent buildings are used by the Navy.

2. Appropriately, Strauss’s statue has been erected in an area close to the bridge. The inscription reads as follows:

1870— Joseph B. Strauss—1938
"The Man who Built the Bridge."
Here at the Golden Gate is the
Eternal Rainbow that he conceived
And set to form, a promise indeed
That the race of man shall
Endure unto the Ages.

Chief Engineer of the Golden Gate Bridge 1929-1937

3. A dramatic test, which the Golden Gate Bridge passed successfully, came on Saturday, December 1, 1951. Between 5:55 P.M. and 8:45 P.M. the bridge was closed to traffic because of a violent storm which generated a gale with a velocity of seventy miles an hour. The deck of the bridge swayed twenty-four feet from side to side and five feet in the perpendicular dimension. Since the bridge was designed to sustain a twenty-seven-foot sway, no serious effects came from this dramatic moment. Close examination of the structure later indicated only minor damage.
